pwndbg_watchpoint

Set a watchpoint to monitor read, write, or read_write access to a memory address or variable during debugging.

Instructions

Set a watchpoint on a memory address or variable.

Args: session_id: The UUID of the session. expression: The variable or address expression to watch. watch_type: Type of access to watch — "read", "write", or "read_write".

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, and description does not disclose side effects (e.g., halting execution, resource consumption) or interactions with debugger state. Minimal behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two lines plus parameter list, no extraneous text. Front-loaded with the core action. Every sentence is useful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers parameters adequately but omits behavioral context like how watchpoints affect debugging (e.g., access triggers) or lifespan. With an output schema present, return value details are less critical, but still could be clearer.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Despite 0% schema description coverage, the description explains each parameter beyond the schema titles: session_id as UUID, expression as variable/address, watch_type with enumerated values. Adds meaningful guidance.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the verb 'Set' and the resource 'watchpoint' on a 'memory address or variable'. Distinguishes from siblings like breakpoint tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like pwndbg_set_breakpoint or pwndbg_set_breakpoint_advanced. Lacks context for prerequisites or scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
